| چکیده | Background and Aim: Mycobacterium tuberculosis has developed resistance to anti-tuberculosis drugs and becoming a major and alarming public health problem in worldwide. This study aimed to determine antituberculosis drug resistance rate and to identify multidrug resistant tuberculosis (MDR-TB) in west of Iran. Methods: Total of 130 samples was included Between Decembers 2011 and July 2012 in the study from that 112 cases were Mycobacterium tuberculosis. The proportional method was carried out according to the CLSI on Lowenstein-Jensen against isoniazid, rifampicin, streptomycin, ethambutol, pyrazinamide, para aminosalsilic acid, etionamid, cyclocerine. The microdillution method was carried out using 7H9 broth with 96 well-plates. Results: From 112 isolates, resistance was observed to isoniazid 18 (16.07%), rifampicin 16 (14.28%), streptomycin 25 (22.32%), ethambutol 15 (13.39%), pyrazinamide 27 (24.10%), para aminosalicylic acid 19 (16.96%), cycloserine 4 (3.57%) and ethionamid 14 (12.5%) cases. 16 isolates were multidrug-resistant. Conclusion: The high prevalence of MDR-TB in our study is assumed to be due to recent transmission of drug resistant strains. Overall, the rate of drug resistance in our study was high, which is in line with findings of some high-burden countries. So that early case detection, rapid drug susceptibility testing, effective anti-TB treatment is necessary. |
